Benefits of technology

[0008]The present invention is directed to image reading apparatuses, image reading methods, and programs for simultaneously reading front and rear surfaces of a document to create a single file in a reduced processing time at low cost.

Problems solved by technology

This requires twice as much time for the encoding, resulting in a longer processing time.
Thus, according to the conventional technique, encoding efficiency becomes low.
Thus, the conventional technique also involves high cost.

Embodiment Construction

[0027]Various exemplary embodiments of the invention will be described in detail below with reference to the drawings. It is to be understood that, unless otherwise specified, the relative positions of components and the like described in the exemplary embodiments are not intended to limit the scope of the invention.

[0028]The following describes a first exemplary embodiment. FIG. 1 is a block diagram illustrating an example of the configuration of an image reading apparatus 100 according to the first exemplary embodiment of the present invention.

[0029]The image reading apparatus 100 is an apparatus configured to read the front and rear surfaces of a document at one time by use of different reading sensors in one document conveying process. Further, the image reading apparatus 100 includes a central processing unit (CPU) 101, a read-only memory (ROM) 102, a storage unit (dynamic random access memory (DRAM)) 103, an operation unit 104, a display unit 105, a reading unit 106, and a sys...

Abstract

An image reading apparatus includes a front surface reading sensor configured to read a front surface of a document, a rear surface reading sensor configured to read a rear surface of the document, a storage control unit configured to store image data of the front surface of the document read by the front surface reading sensor and image data of the rear surface of the document read by the rear surface reading sensor, and an encoding unit configured to encode image data of the paired front and rear surface images based on the image data of the front surface and the image data of the rear surface.

Description

BACKGROUND OF THE INVENTION[0001]Field of the Invention[0002]The present invention relates to image reading apparatuses configured to store simultaneously-read images of front and rear surfaces of a document as a single file in a memory.[0003]Description of the Related Art[0004]Techniques for simultaneously reading front and rear surfaces of a document and creating a single file are known. Japanese Patent Application Laid-Open No. 8-022536 discusses a technique for simultaneously reading front and rear surfaces of a document and creating a single file, and image data of the front and rear surfaces are stored in different buffers and the stored image data are encoded by an encoding apparatus.[0005]More specifically, the image data of the read front surface is temporarily stored in a buffer memory 16 of a system main unit 3, and the image data of the read rear surface is stored in a buffer memory 10 having a capacity corresponding to one document page. Then, a data compression / decompr...
